WASHINGTON (AFX) -- Factory activity in the United States decelerated in December after strong showings in the past three months, the Institute for Supply Management reported Tuesday. The ISM index fell to 54.2% in December from 58.1% in November. This is the biggest monthly decline since July 2002. The decline was larger than expected. The consensus of estimates collected by MarketWatch called for a modest decline in the index to 57.6% in December. Stock market gains wilted after the ISM report was released. The dollar fell to its lowest level of the trading day and bonds pared early declines on the sense that the factory sector was moderating
Norbert J. Ore, chair of the ISM manufacturing business survey committee, said the decline was natural after three strong months and that the factory sector retains significant momentum going into 2006
Economists cautiously agreed with the assessment
"We can't see any good reason why this should mark the start of a sustained softening in the ISM, but another softish report next month would be worrying," said Ian Shepherdson, chief U.S. economist at High Frequency Economics
